Problems with the puzzles on Chess.com

I'm advised to do the puzzles on this website (https://www.chess.com/article/view/study-plan-beyond-the-basics) but I don't see the benefit of doing that when I can't find out why a certain move is the solution, or why another move isn't - I can't find feedback on the moves. For instance, I got this puzzle today

...and I honestly can't find out why the solution is the best move. In the meantime I give all the wrong answers and my rating has plummeted 😄 (not that I really care).

So my question is: how am I actually going to learn from these daily puzzles? I'm an absolute beginner and like to stay motivated 🤗

You can use the analysis button at the end of the puzzle (use hints till you get to the solution). It will show you the computer analysis; you have to make the first (automatic) move of the puzzle yourself. 

P.S. mijn username is geen grapje naar jou toe, maar gewoon al een paar jaar mijn username.

Thanks. So that analysis button explains why a certain move is the best move? I'll try that out later as I am out of my free puzzles for today.

😊 ik vind 'm wel leuk gevonden

Nice

Well.... the analysis button gives the computer analysis of the different moves you can play; that way you can may be figure it out by trying different moves and seeing what the computer suggests.

There is no king on that puzzle
